Himiko

Ina is the god-child of Fire, born in a small village in the mountains, called Inasa. There, she meets a man who wandered in from another country called Susa, and thus begins their fantastic story of love and growth. Kurashina Ryou, famous for his "Empress" series, now begins a fresh new story with the skilled artist Minami Megumu! After her father, the village leader dies, she announces that she will become the new leader. Then, a manly wanderer with a type of sword that she's never seen before appears... later she will come to be known as Himiko, and through the power of the pure swordsman named Susano-o and Hihiirokane, the two begin their journey on the path to the power struggle filled creation of Yamatai! Minami Megumu, a flaship web comic artist, draws their love story with sharp touches and beautiful curves. This is the "Powered-up version" of Empress!
